For the Arizona private school education tax credit in 2025, the maximum contribution is $1,535 for single filers and $3,062 for married filing jointly. The donation amount is capped by the state limit or your Arizona tax liability, whichever is less.

2025 limits

  • Single: $1,535.
  • Married filing jointly: $3,062.

What that means

You can donate up to those amounts and claim the credit, but you cannot claim more than your actual Arizona tax owed. The limit is split between the original credit and the PLUS/extra credit, which together make up the total maximum.

Simple example

If you file single and donate $1,535 to a qualifying school tuition organization in 2025, that is the maximum private-school tax-credit donation for that filing status.

TL;DR: $1,535 single, $3,062 married filing jointly for 2025.
